Standard Specification for Less-Flammable Synthetic Ester Liquids Used in Electrical Apparatus 电气设备用不易燃合成酯液体的标准规范
发布日期: 2022-07-15
1.1 本规范涵盖了新的和现有的电力设备(包括电力和配电变压器、开关设备和其他相关设备)中用作电介质和冷却的不易燃(高燃点)合成酯绝缘液体 1.2 合成酯绝缘液体不同于传统矿物油和其他不太易燃(高燃点)的液体,因为它们是由羧酸和醇的化学反应、加工和物理处理产生的产物。 1.3 本规范旨在定义与现有设备的典型结构材料兼容的合成酯电绝缘液体,并有望在这些应用中保持其功能特性。 本规范中描述的材料并不总是与其他电绝缘液体混溶。用户应联系合成酯绝缘液体的制造商以获得这方面的指导。 1.4 本规范仅适用于任何加工前收到的未使用的合成酯绝缘液体。如果对推荐的特性或液体维护程序有疑问,用户应联系设备或液体或两者的制造商。 1.5 以国际单位表示的值应视为标准值。本标准不包括其他计量单位。 1. 6. 本标准并不旨在解决与其使用相关的所有安全问题(如有)。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践,并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。
1.1 This specification covers less-flammable (high fire point) synthetic ester insulating liquids for use as a dielectric and cooling in new and existing electrical power apparatus including power and distribution transformers, switchgear, and other associated equipment 1.2 Synthetic ester insulating liquids differ from conventional mineral oil and other less-flammable (high fire point) liquids in that they are products derived from the chemical reaction, processing, and physical treatments of a carboxylic acid and an alcohol. 1.3 This specification is intended to define synthetic ester electrical insulating liquids that are compatible with typical materials of construction of existing apparatus and are expected to maintain their functional characteristics in these applications. The material described in this specification is not always miscible with other electrical insulating liquids. The user should contact the manufacturer of the synthetic ester insulating liquid for guidance in this respect. 1.4 This specification applies only to unused synthetic ester insulating liquids as received prior to any processing. The user should contact the manufacturer of the equipment or liquid, or both, if questions of recommended characteristics or liquid maintenance procedures arise. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
